Special-purpose light-guiding seat for pilot lamps of an electronic machine

ABSTRACT

A special-purpose light-guiding seat for pilot lamps of an electronic machine, which comprises a fixing base, a light-guiding device, and a light-pervious block, is basically mounted on an electronic machine housing for indicating the state of inside light sources (LED), in which the light-guiding device is substantially a transparent rod body having its front end connected with the light-pervious block while its tail end is extended to approach the light source; and the light-pervious block is jointed with the fixing base such that the outer-edge surface of the light-pervious block can be inserted and fixed flush on the machine housing for people to view from outside the lighting state of the light-pervious block easily and distinctly.

FIELD OF THE INVENTION

[0001] The present invention relates generally to a light-guiding seat,and in particular to a special-purpose light-guiding seat for pilotlamps of an electronic machine.

BACKGROUND OF THE INVENTION

[0002] A light-emitting diode (LED) could be detached from an inside PCboard and extended to be installed on the housing of an electronicmachine (computer, IA, etc.) for showing the lighting state of the LED,however, a job like this is such troublesome and lack of stableness thatpeople usually don't want to take. Instead, a widely adopted way is tomove the LED together with a PC board as closer as possible to apredetermined through hole in the machine housing for showing itslighting state clearly through a light-pervious block. This manner isestablished on the premise of a shortest clearance between the LED andthe light-pervious block that entails difficult conditions inarrangement of the PC board and the light source and the available spacebetween them. Moreover, cross interference of neighboring light-perviousblocks might be incurred to confuse people of the lighting state of thelight-pervious blocks that needs to be distinctly isolated.

SUMMARY OF THE INVENTION

[0003] The primary objective of this invention is to provide aspecial-purpose light-guiding seat for pilot lamps of an electronicmachine having the following merits:

[0004] 1. The state of an inside light source can be shown clearly in alight-pervious block;

[0005] 2. The light of a remote light source can be converged andtransmitted to a light-pervious block via a light-guiding device tosimplify design of a substrate and the machine housing and enlarge thespace thereof; and

[0006] 3. The light transmitted from a remote light source to alight-pervious block on the machine housing wouldn't be attenuatedsignificantly.

[0007] In order to obtain said merits, the light-guiding device isadopted to converge and transmitted light to outside of the machinehousing to thereby simplify the assembly of light sources. Aspecial-purpose light-guiding seat for pilot lamps of an electronicmachine, comprised of a fixing base, a light-guiding device, and alight-pervious block, is basically mounted on the machine housing forindicating the state of inside light sources (LED), in which thelight-guiding device is substantially a transparent rod body having itsfront end connected with the light-pervious block while its tail end isextended to approach the light source; and the light-pervious block isjointed with the fixing base such that the outer-edge surface of thelight-pervious block can be inserted and fixed flush on the machinehousing for people to view from outside the lighting state of thelight-pervious block easily and distinctly.

[0008] For more detailed information regarding advantages or features ofthis invention, at least an example of preferred embodiment will befully described below with reference to the annexed drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0015]FIG. 1 is a three-dimensional view of an embodiment of thisinvention showing a special-purpose light-guiding seat 1 for pilot lampsof an electronic machine at a proper position for guiding the lightemanated by inside light sources (usually LEDs) 4 and showing it on amachine housing 2.

[0016] The light-guiding seat 1 is made of a transparent materialintegrally and mainly comprised of a fixing base 11, a light-guidingdevice 13, and a light-pervious block 12, in which the light-guidingdevice 13 is substantially a transparent rod body having its front endconnected with the light-pervious block 12 while its tail end isextended to approach the light source 4; and the light-pervious block 12is jointed with the fixing base 11 such that the outer-edge surface ofthe light-pervious block 12 can be flush inserted on the machine housing2 for people to view externally the lighting state of the light-perviousblock 12. Besides, the fixing base 11 is fixedly located at a suitableposition directly on the machine housing or on some other component ordevice inside the machine housing 2. When a remote light source (LED) 4is lightened, light emitted is converged to the light-pervious block 12via the transparent light-guiding device 13 to thereby transfer thelight from the light source effectively.

[0017] According to the respective assembly embodiments (I) and (II) ofthis invention shown in FIGS. 2 and 3, a special-purpose light-guidingseat for pilot lamps of an electronic machine is constructed byarranging a plurality of light-pervious blocks 12 and light-guidingdevices 13 on a fixing base 11, in which the amount of thelight-pervious block 12 and the light-guiding device 13 are equal anddetermined depending on the amount of a light source 4, and both thelight-pervious block 12 and the light-guiding device 13 are made of atransparent material. Moreover, the light-guiding device 13 could be arod body having its front end connected with the light-pervious block 12while its tail end is extended to approach the light source 4. Also, thelight-guiding device 13 and the light-pervious block 12 are fixedtogether at a suitable position inside the machine housing 2 such thatthe light-pervious block 12 can be snap-retained in a through hole 21 ofthe machine housing 2 in the way that the surface of the light-perviousblock 12 is flush with or protrusive from that of the machine housing 2.When the remote light source 4 is lightened, the light is transmitted toand shown in the light-pervious block 12 through the light-guidingdevice 13. The fixing base 11 could be bar-shaped and provided withseveral through holes 111, through which the fixing base 11 can beconnected to some fixing members 22 on the machine housing 2 by way offusion connection (or by screwing or referring to FIGS. 4 and 5).

[0018] According to the respective cutaway sectional views (I) and (II)of this invention shown in FIGS. 4 and 5, a light-guiding seat 1 iscomprised of a fixing base 11, a light-pervious block 12, and alight-guiding device 13, in which the light-guiding device 13 and thelight-pervious block 12 are made of a transparent material and fixedtogether to the fixing base 11; and the front end of the light-guidingdevice 13 is jointed with the light-guiding block 12, and its tail endis arranged approaching a light source 4 on a substrate 3. When thelight source 4 is lightened, the light is transmitted to and shown inthe light-pervious block 12 through the light-guiding device 13, andmeanwhile, because the surface of the light-pervious block 12 isprotruded in air over the machine housing 2, hence, the light shown inthe light-pervious block 12 can be viewed by people.
